The Prophet Habakkuk
Hospital de los Venerables Sacerdotes, Seville, Spain
The prophet wears a variation of the quasi-priestly garments in the nearby portrait of King David.
The phrase on his shield is from Habacuc 3:9a: Suscitans suscitabis arcum tuum, juramenta tribubus quae locutus es. Cant. Habacuc Cap. 3. ("Thou wilt surely take up thy bow: according to the oaths which thou hast spoken to the tribes. Canticle of Habakkuk Chapter 3"). The Canticle of Habakkuk is an evocation of the terrible power of God's wrath.
Habakkuk also appears in a large number of paleo-Christian images of Daniel's sojourn in the lions' den.
